IGNORED HYPOTHESIS. “Though I’ve read numerous articles struggling to explain away the Cambrian explosion, I’d never heard of anyone arguing that the alleged Precambrian ancestors to the Cambrian animals were missing because the strata containing their fossils had been completely eroded from the face of the earth in such a “Great Unconformity.” But after hearing this objection, I did some research. I discovered a single place where this argument has been made: It was over 100 years ago by Charles Doolittle Walcott, the famous geologist who discovered the Burgess Shale. Apparently the argument was never adopted by subsequent geologists, for good reasons.”
